Filter frame sealing structure

The utility model relates to a filter frame sealing structure which comprises a corner sealing piece, a sealing piece and a sealing piece, and the corner sealing piece is matched with the corner of a frame to be bent; the straight edge sealing pieces are located between the adjacent corner sealing pieces; an embedding part is arranged at the end of the straight edge sealing piece, an embedding groove is formed in the end of the corner sealing piece, the embedding part is clamped and embedded in the embedding groove, and the embedding groove is only provided with an opening and faces the embedding part. The top of the embedding part slightly protrudes out of the surface of the straight-edge sealing piece. According to the sealing structure, the sealing effect can be more effectively achieved under the action of external force, and the air leakage condition is reduced. 本申请涉及一种过滤器框架密封结构，其包括：转角密封件，转角密封件匹配框架的边角弯折；直边密封件，直边密封件位于相邻的转角密封件之间；直边密封件的端部设有嵌合部，转角密封件的端部设有嵌合槽，嵌合部卡嵌在嵌合槽内，嵌合槽仅具有一个开口且朝向嵌合部设置；嵌合部顶部略微凸出直边密封件表面。本申请
